1

how an organism's structure, physiology, and behavior meet the challenges posed by its environment

organismal ecology

2

analyzes factors that affect population size and how and why it changes through time

population ecology

3

examines how interactions between species, such as predation and competition, affect community structure and organization

community ecology

4

emphasizes energy flow and chemical cycling between organisms and the environment

ecosystem ecology

5

focuses on the factors controlling exchanges of energy, materials, and organisms across multiple ecosystems

landscape ecology

6

examines how the regional exchange of energy and materials influences the functioning and distribution of organisms across the biosphere

global ecology

7

advocates the protection of nature

environmentalism

8

is not an advocate, just a study of the environment

ecology

9

nonliving factors such as chemical and physical factors

abiotic factors

10

living factors, such as all the organisms that are part of the individual's environment

biotic factors

11

the movement of individuals away from their area of origin of from centers of high population density

dispersal

12

a narrow layer of abrupt temperature change that separates the more uniformly warm upper layer from more uniformly cold deeper waters

thermocline

13

where the oxygenated water from a lake's surface goes to the bottom and the nutrient rich water from the bottom to the surface

turnover

14

lakes that are nutrient-poor and generally oxygen rich

oligotrophic lake

15

a lake that's nutrient-rich and often depleted of oxygen

eutrophic lake

16

inundated by water at least some of the time

wetlands

17

most prominent physical characteristic is their current

streams and rivers

18

transition area b/t river and sea

estuary

19

periodically submerged and exposed by the tides, twice daily on most marine shores

intertidal zones

20

vast realm of open blue water, constantly mixed by wind-driven oceanic currents

ocean pelagic zone

21

formed largely from the calcium carbonate skeletons of corals

coral reef

22

consists of the seafloor below the surface waters of the coastal, or neritic, zone, and the offshore, pelagic zone

marine benthic zone

23

number of individuals per unit area of volume

density

24

the pattern of spacing among individuals within the boundaries of the population

dispersion

25

used to estimate the size of wildlife populations

Mark-recapture method

26

grouped together where food is abundant

clumped

27

maintained by aggressive interactions between neighbors

uniform

28

most plants use this pattern of dispersion

random

29

study of the vital statistics of populations and how they change over time

demography

30

age specific summaries of the survival pattern of a population

life tables
